Weekly Quiz Competition

Question 1
1 / -0

The organic manure is considered better than fertilisers because

A
It can be prepared in the factories.

B
It is less rich in plant nutrient.

C
It improves the texture of the soil.

D
It decreases the water holding capacity of the soil.

Solution

Organic manure contains a high amount of organic matter which increases the capability of the soil to hold water. They are prepared by the decomposition of organic matter by the microbes. They are rich in plant nutrients. They also help to improve the quality and texture of the soil as they form humus, which is hygroscopic. The gaseous exchange takes place easily in this soil which allows the germination and growth of the plants properly.
Thus, the correct answer is option C.
Question 2
1 / -0

The growing two or more crops at a time in a field is called as

A
Crop rotation

B
Inter cropping

C
Mixed cropping

D
None of the above

Solution

When the same land is used for the cultivation of more than one crop is known as mixed cropping. The same field is divided into smaller regions. The seeds of different crops are sown and cultivation of different crops is carried out in the same piece of land.
Thus, the correct answer is option C.
Question 3
1 / -0

Which of these is not used for improving crop yield?

A
Crop protection management

B
Crop production management

C
Crop variety improvement

D
Crop transport management

Solution

Nowadays, different types of management programs are undertaken to improve the yield of crop plants. Crop protection, production, and variety improvement are the management programs that help to enhance the yield of the crop. Transport management is not a part of crop yield increase. Transport management facilitates the transport of foodgrains and vegetables from the field to the market or godowns.
Thus, the correct answer is option D.
Question 4
1 / -0

Which of the following is true for animal husbandry?

A
Animal husbandry is the management and care of farm animals by humans, in which genetic qualities and behaviour, considered to be advantageous to humans, are further developed.

B
In addition to supplying milk, meat, eggs, wool and hides, animals, mainly bullocks, are the major source of power for farmers.

C
Both A and B

D
Animal husbandary is the art and science of cultivating the soil, growing crops.

Solution

Animal husbandry is the management and care of farm animals by humans, in which genetic qualities and behavior, considered to be advantageous to humans, are further developed. A large number of farmers in India depend on animal husbandry for their livelihood. In addition to supplying milk, meat, eggs,wool and hides, animals, mainly bullocks, are the major source of power for farmers.
So, the correct answer is option C-'Both A and B'.
Question 5
1 / -0

Which of the following methods of cultivation will result in the loss of soil fertility?
I.Crop rotation
II. Inter-cropping
III. Excessive use of chemical fertilizers

A
I and II only

B
III only

C
I and III only

D
I, II and Ill

Solution

When there is excessive use of chemical fertilizers and pesticides, the chemical salts accumulate in the soil and affect the quality and fertility of the soil.
Crop rotation (growing of different crops on a piece of land in pre-planned succession) and inter-cropping (growing two or more crops in definite row patterns) methods are types of cropping patterns that are used to maintain the fertility of the soil.
Thus, the correct answer is option B.
Question 6
1 / -0

What is the advantage of crop rotation?

A
Getting different kinds of crops

B
Increasing the quality of minerals

C
Increasing the fertility of soil

D
Increasing the quality of proteins
Solution
Crop rotation is a traditional practice of growing different crops in the same area, so as to increase the fertility of the soil.
This process helps to build up the lost nutrients of the soil and when the rotation is done with growing cereals, it replenishes the nitrogen levels of the soil because crop rotation is mostly done by using legumes and paddy crops.
So, the correct answer is option C.
Question 7
1 / -0

Which of the following is a food-fodder mixed farming system?

A
Growing food crops alone

B
Growing fodder crops alone

C
Growing crops which can be used as food and fodder by using more fertilizers.

D
Growing food crops and fodder crops in the same field.

Solution

Growing food crops and fodder crops together in a field is a food-fodder mixed farming system. In this agricultural system, a farmer grows crops like rice, wheat or cash crops together with fodder crops like sorghum, oat, etc. to increase the income through different sources.
So, the correct answer is option D.
Question 8
1 / -0

Which of the following cropping methods maintains soil fertility?
(i) Mixed farming
(ii) Crop rotation
(iii) Mono cropping

A
Only (i)

B
(i) and (ii)

C
(ii) and (iii)

D
(i), (ii) and (iii)
Solution
- Mixed farming is the process of growing crops and livestock animals in same areas of land.
- In mixed farming manure is available from livestock animals maintains soil fertility.
- Crop rotation is the method of cultivation in which different crops are cultivated on the same land in successive seasons. It helps to maintain the soil productivity.
- Mono cropping is the pattern of cropping of a similar type of plant in the same land throughout the year. It reduces the biodiversity and increases the difficulty in nutrient cycling.
- Thus, the correct answer is option B.
Question 9
1 / -0

Which of the following characteristic can be obtained when quality breeding is done?

A
Higher yields of crop in a shorter period of time

B
Cropping without irrigation

C
Increased lifespan of crops by 10 years

D
Carrying out photosynthesis at night

Solution

Varieties or strains of improved crops can be selected by quality breeding for various useful characteristics such as disease resistance, response to fertilisers, product quality and high yields.
So, the correct answer is option A.
Question 10
1 / -0

The trait which is accounted for hybridization is

A
Resistance to diseases

B
Productivity

C
Tolerance to climatic condition

D
All of the above
Solution
- The crossing between two plants of different species to produce a new variety is called hybridization.
- The new plant which is produced is known as the hybrid which possesses superior characters of both the parent plants.
- The traits which are considered for hybridization are resistance to pests, insects and diseases, an increase in productivity and high yielding, tolerance to adverse conditions, etc.
Thus, the correct answer is option D.
